GEORGE T. ROSSELLE, 01E NEWPORT, KENTUCKY, ASSIG-NOR TO THE INCANDESCENT LIGHT & STOVE COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.

GENERATOR FOR HYDEOCARBON sYSTEMs.

To all whom it may concern:

Be it known that I, GEORGE T. RossELLE, a citizen of the United States, residing at Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Generators for Hydrocarbon Systems, of which the following is a specification.

My invention relates to an improvement in hydrocarbon vapor generators.

One of the objects of the invention is to provide means for superheating the vapor before it enters the needle valve, the superheating chamber and its relation to the generator proper being such that the deposit of carbon will not clog any of the passages through which the vapor passes to the me dle valve.

Another object of the invention is to provide means for preventing the liquid hydrocarbon from boiling over from the generator into the super-heating chamber.

Another object of the invention is to produce a simple, cheap, compact and eflicient combined generator and super heating chamber.

Another object of the invention is to provide means for uniformly heating the walls of both generator and super-heating chamber.

Another object of this invention is to produce a combined generator and super heating chamber, of such construction and arrangement, relative to one another and to the sub -burner, that the vapor will be uniformly super-heated, irrespective of the quantity being generated.

The features of my invention will be more particularly set forth in the description of the accompanying drawing, forming a part of this specification, in which Figure 1 is a side elevation of my improvement. Fig. 2 is a central vertical sec tion through the combined generator and super-heating chamber. Fig. 3 is a section on line 00, Fig. 2.

1 indicates the liquid hydro-carbon tank.

2 represents the casting containing the generating and super-heating chamber. ithin said casting 2 is a vertical partition 3, having a horizontal floor 1, connected to one of the side walls of the casting 2, at a point slightly above the bottom of the cast ing 2. Preferably, the bottom has a screw threaded plug 5, engaging into the lower Specification of Letters Patent.

end of the casting 2 and forming the lower end of the generating compartment. This partition 3 extends upwardly to a position near the upper end of the casting 2, terminating at a point above the highest liquid level of the hydro-carbon in the generating compartment. Thus, the said partition 3 defines, within the chamber or casting 2, a generating compartment 6, and a superheating compartment 7 separated at their lower ends and in free communication at their upper ends.

8, 9, represent pipes connecting the top and bottom respectively of the liquid tank 1 and the generating compartment 6. Preferably, that portion of the generator 6, which lies above the pipe 8, is filled with a granular packing 10, preferably gravel, the function of which is to elevate the liquid hydrocarbon in the generator in a diffuse condition, and T have found that this arrangement prevents the liquid hydro-carbon from boiling over into the vapor super-heating chamber. Preferably, the casting 2 is formed with a horizontal extension 11, forming a part of the super-heating chamber 7, and positioned at the lower portion of the casting 2.

12 represents an annular sub-burner surrounding the chamber 2 at a position just under the horizontal extension 11. This sub-burner has the horizontal jets 13, which cause the generating flame to impinge substantially perpendicularly against the walls of the casting 2, thus serving to uniformly heat both the generating and super-heating compartments, irrespective of the size of the sub-burner flame. The generating and super-heating compartments, preferably have the same cross sectional area, and the heating surfaces of said compartments are of predetermined proportional area. It will thus be seen that the sub-burner is positioned just under the vapor outlet 14, leading from the super-heating compartment to the needle valve 15, so that the super-heating and generating compartments extend downwardly to a point somewhat below the plane of the sub-burner. Thus,the sub-burner not only heats the liquid hydro-carbon at a point where it is held by the filling 10, above the pipe 8, but it superheats the vapor at a point below the horizontal plane of outlet 14, where the vapor enters the needle valve. The carbon which will be deposited at the point where the highest'degree of heat is applied, will adhere to those portions of the walls of the superheating chamber 7, which lie below the vapor outlet 14, so that with this construction and arrangement it is impossible to clog or impede any portion of the structure through which the vapor must pass from the generator into the needle valve.

16 represents the air mixer cooperating with the needle valve 15.

17 represents the service-pipe into which the vapor and air are entrained.

18, 19, represent pipes leading from the service-pipe to the sub-burner 12, for supplying the latter. Thetop and bottom connection of the generator and tank is important, as it equalizes the vapor pressure above the liquid level, and prevents thegasolene from being forced backinto the tank, whe n the generator is heated, or into the super heater when the sub-burner is shut ofil The simplicity, compactness, efiiciency and new and usefulfunctions of this combined generator and super-heating chamber, will be fully understood bythose skilled in the. art from the abovedisclosure. By this partition two compartments are formed lying upon each side of the chamber, so. that theirwalls are in common, thus the flame of the annular sub-burner plays directly upon the exterior 'wall of 'boththe generating and the super-heating compartments so that they are proportionately heated in the ratio'of the area oft-he wall directly subjected to the sub-burner flame. a Havingdescribed my invention, I claim: 1 ..In a device of-th'e class described, a chamber divided by a partition into two vertical compartments communicating at the top, a liquid hydro-carbon supply to one of sai'dcompartme-nts, a vapor outlet from the other compartment, and a sub-burner surrounding the lower portion of said chamber at-apoint below the vapor outlet. 7 '2. In' a device oftheclass described, a chamber formed with'two vertical compartments, communicating at thetop, aliquid hydro-carbonsupply to one of sa-id-compartments, a vapor outlet from the other compartment, and an annular sub-burner surrounding said chamber at a point below the vapor outlet, 'thelower extremities of saidcompartments extend-ing to a point be low' the flame of the sub-burner.

4.
